実施の形態１．
図１は、本発明にかかるパワーコンディショナの実施の形態１の構成を示す図である。外郭筐体１の内部には、太陽電池モジュールからの直流電力を交流電力に変換するインバータユニットが実装された電子回路基板や開閉器２を始めとする電気部品からなる電気回路部３が収められており、電気回路部３は、保護カバー４で覆われて保護されている。 Embodiment 1 FIG.
FIG. 1 is a diagram showing a configuration of a power conditioner according to a first embodiment of the present invention. Inside the outer casing 1 is housed an electric circuit unit 3 composed of an electronic circuit board on which an inverter unit for converting DC power from a solar cell module into AC power is mounted, and an electrical component such as a switch 2. The electric circuit unit 3 is covered and protected by a protective cover 4.

図２は、実施の形態１にかかるパワーコンディショナに適用される開閉器の構造を示す図である。開閉器２は、太陽電池モジュールからの電力の電路を開閉する機器である。開閉器２は、本体部分２ａと、本体部分２ａに対し移動することによって開位置及び閉位置のいずれかに配置される開閉レバー５とを有する。開閉器２は、太陽電池モジュールからの電力の電路上に設置されており、開閉レバー５が開位置及び閉位置のいずれに配置されるかにより、本体部分２ａの内部で電気の流れが開閉されるようになっている。開閉器２としては、一般的なものを適用可能である。   FIG. 2 is a diagram illustrating a structure of a switch applied to the power conditioner according to the first embodiment. The switch 2 is a device that opens and closes an electric circuit for power from the solar cell module. The switch 2 has a main body portion 2a and an open / close lever 5 that is arranged in either the open position or the closed position by moving with respect to the main body portion 2a. The switch 2 is installed on the electric path of the electric power from the solar cell module, and the flow of electricity is opened and closed inside the main body portion 2a depending on whether the open / close lever 5 is arranged in the open position or the closed position. It has become so. A general switch can be applied as the switch 2.

図３は、閉じた状態の開閉器と保護カバーとの関係を示す図である。開閉レバー５には、取り外し防止キャップ６が装着されている。取り外し防止キャップ６は、開閉レバー５の先端を覆う被覆部６ａと、被覆部６ａから鍔状に張り出して延在する延在部６ｂとを備えている。図３に示すように、開閉レバー５に装着された取り外し防止キャップ６の延在部６ｂは、開閉器２が閉じた状態（ＯＮ状態）では、保護カバー４の開口４ａ以外の部分と投影面で重なっている。すなわち、取り外し防止キャップ６は、開閉レバー５が閉位置に配置された状態では、延在部６ｂが開口４ａの外にはみ出して保護カバー４にかかっている。これにより、開閉器２が閉じた状態で保護カバー４を外そうとしても、取り外し防止キャップ６が保護カバー４と干渉し、保護カバー４を外すことはできなくなっている。   FIG. 3 is a diagram illustrating the relationship between the switch in the closed state and the protective cover. A removal prevention cap 6 is attached to the opening / closing lever 5. The removal prevention cap 6 includes a covering portion 6a that covers the tip of the opening / closing lever 5, and an extending portion 6b that extends from the covering portion 6a and extends in a hook shape. As shown in FIG. 3, the extension portion 6b of the removal preventing cap 6 attached to the opening / closing lever 5 has a projection surface and a portion other than the opening 4a of the protective cover 4 when the switch 2 is closed (ON state). Are overlapping. That is, in the state in which the opening / closing lever 5 is disposed at the closed position, the removal preventing cap 6 extends over the protective cover 4 with the extending portion 6b protruding outside the opening 4a. Thereby, even if it is going to remove the protective cover 4 in the state where the switch 2 is closed, the removal preventing cap 6 interferes with the protective cover 4 and the protective cover 4 cannot be removed.

図４は、開いた状態の開閉器と保護カバーとの関係を示す図である。図４に示すように、開閉器２が開いた状態（ＯＦＦ状態）であると、取り外し防止キャップ６の保護カバー４への投影像は、保護カバー４の開口４ａの内側に収まる（取り外し防止キャップ６の投影像が開口４ａからはみ出さない）ため、延在部６ｂが保護カバー４と干渉することはなく保護カバー４を外すことが可能となる。   FIG. 4 is a diagram illustrating a relationship between the switch in the opened state and the protective cover. As shown in FIG. 4, when the switch 2 is in an open state (OFF state), the projection image of the removal prevention cap 6 on the protective cover 4 fits inside the opening 4 a of the protection cover 4 (removal prevention cap). 6 does not protrude from the opening 4a), the extending portion 6b does not interfere with the protective cover 4, and the protective cover 4 can be removed.

取り外し防止キャップ６を開閉レバー５に装着した状態であっても、開閉器２のＯＮ／ＯＦＦを切り替える操作はユーザが任意のタイミングで行うことができる。   Even in a state where the removal prevention cap 6 is attached to the open / close lever 5, the user can perform an operation of switching the switch 2 ON / OFF at an arbitrary timing.

本実施の形態によれば、開閉器２を開いた状態（ＯＦＦ状態）としない限り保護カバー４を外せない構造を実現するために追加する必要がある部品は、開閉レバー５に装着する取り外し防止キャップ６のみであるため、安全性の高い構造を低コストで実現できる。   According to the present embodiment, components that need to be added to realize a structure in which the protective cover 4 cannot be removed unless the switch 2 is opened (OFF state) are prevented from being attached to the switch lever 5. Since only the cap 6 is provided, a highly safe structure can be realized at low cost.

実施の形態２．
図５は、本発明にかかるパワーコンディショナの実施の形態２に適用される多極開閉器の構造を示す図である。本明細書において多極開閉器とは、各々の開閉レバー５が開閉レバー接続部品８によって連動し、ＯＮ／ＯＦＦ操作が同時に行われるように連結された複数個の開閉器を指す。すなわち、多極開閉器７は複数の開閉レバー５を連結する開閉レバー接続部品８を備えている。個々の開閉器は、実施の形態１と同様である。 Embodiment 2. FIG.
FIG. 5 is a diagram showing the structure of a multipolar switch applied to Embodiment 2 of the power conditioner according to the present invention. In the present specification, the multipolar switch refers to a plurality of switches that are connected so that each open / close lever 5 is interlocked by the open / close lever connecting component 8 and the ON / OFF operation is performed simultaneously. That is, the multipolar switch 7 includes an opening / closing lever connecting component 8 that connects the plurality of opening / closing levers 5. The individual switches are the same as those in the first embodiment.

図６は、閉じた状態の多極開閉器と保護カバーとの関係を示す図であり、図６（ａ）は正面図、図６（ｂ）は側面図である。本実施の形態においては、保護カバー４の開口４ａの縁には、開閉レバー５の閉位置の側から開位置の側に向かって凸となる凸部４ｂが設けられており、保護カバー４の開口４ａは凹形となっている。多極開閉器７が閉じた状態（ＯＮ状態）では、開閉レバー接続部品８の保護カバー４への投影像は、保護カバー４の凸部４ｂと重なるため、保護カバー４を外そうとすると、開閉レバー接続部品８が保護カバー４と干渉する。換言すると、開閉レバー接続部品８は、多極開閉器７の開閉レバー５が閉位置に配置された状態では、凸部４ｂと重なっている。したがって、多極開閉器７が閉じた状態では、保護カバー４を外すことはできなくなっている。   6A and 6B are diagrams showing the relationship between the closed multipolar switch and the protective cover, in which FIG. 6A is a front view and FIG. 6B is a side view. In the present embodiment, the edge of the opening 4 a of the protective cover 4 is provided with a convex portion 4 b that protrudes from the closed position side of the opening / closing lever 5 toward the open position side. The opening 4a is concave. When the multipolar switch 7 is closed (ON state), the projection image of the opening / closing lever connecting component 8 onto the protective cover 4 overlaps the convex portion 4b of the protective cover 4, so when the protective cover 4 is to be removed, The opening / closing lever connecting component 8 interferes with the protective cover 4. In other words, the open / close lever connecting component 8 overlaps the convex portion 4b in a state where the open / close lever 5 of the multipolar switch 7 is disposed at the closed position. Therefore, the protective cover 4 cannot be removed when the multipolar switch 7 is closed.

図７は、開いた状態の多極開閉器と保護カバーとの関係を示す図であり、図７（ａ）は正面図、図７（ｂ）は側面図である。図７に示すように、多極開閉器７が開いた状態（ＯＦＦ状態）であると、開閉レバー接続部品８の保護カバー４への投影像は、保護カバー４の凸部４ｂと重ならないため、保護カバー４を外すことが可能となる。   FIGS. 7A and 7B are diagrams showing the relationship between the multipolar switch and the protective cover in an open state, in which FIG. 7A is a front view and FIG. 7B is a side view. As shown in FIG. 7, when the multipolar switch 7 is in an open state (OFF state), the projection image of the open / close lever connecting component 8 on the protective cover 4 does not overlap the convex portion 4 b of the protective cover 4. The protective cover 4 can be removed.

多極開閉器７のＯＮ／ＯＦＦを切り替える操作はユーザが任意のタイミングで行うことができる。   An operation for switching the ON / OFF of the multipolar switch 7 can be performed by the user at an arbitrary timing.

本実施の形態によれば、保護カバーの開口に凸部を設けるだけで、多極開閉器を開いた状態（ＯＦＦ状態）としない限り保護カバーを外せない構造を実現できるため、安全性の高い構造を低コストで実現できる。   According to the present embodiment, it is possible to realize a structure in which the protective cover can be removed only by providing a convex portion at the opening of the protective cover unless the multipolar switch is opened (OFF state). The structure can be realized at low cost.

以上のように、本発明にかかるパワーコンディショナは、安全性の高い構造である点で有用である。   As described above, the power conditioner according to the present invention is useful in that it has a high safety structure.
